The solid-phase total synthesis of the proposed structure of cyclic depsipeptide coibamide A and its derivative O-desmethyl coibamide A is reported. In this study, we demonstrate the solid-phase synthetic strategy and final solution-phase O-methylation for highly N-methylated cyclic depsipeptides. On-resin macrocyclization, N,N-dimethylation and solution-phase O-methylation were the key steps of these
报道了环状缩酚酚醛酰胺 A 及其衍生物 O-去甲基 coibamide A 的拟议结构的固相全合成。在这项研究中,我们展示了高度 N-甲基化环状缩肽的固相合成策略和最终溶液相 O-甲基化。树脂上大环化、N,N-二甲基化和液相O-甲基化是这些合成的关键步骤。根据液相色谱-质谱 (LCMS) 分析,合成 coibamide A 的质量与天然产物的质量一致,但在 1H 和 13C NMR 分析中观察到显着差异。

A buildingblock approach to the synthesis of YM- and FR-analogs has been developed and utilized for the synthesis of YM-385781. The structure of the final analog was confirmed both spectroscopically and through biological assays, and it was interesting to note that even the less potent synthetic analog made here was able to inhibit both oncogenic Gq signaling and uveal melanoma cell growth.
已开发出合成 YM 和 FR 类似物的构建模块方法,并将其用于 YM-385781 的合成。最终类似物的结构通过光谱和生物测定得到证实,有趣的是,即使是这里制造的效力较低的合成类似物也能够抑制致癌的 Gq 信号传导和葡萄膜黑色素瘤细胞的生长。
